Electrical Contractors, Designers, Electricians and Lighting Specialists can solve tough electrical calculations in seconds and deliver those solutions in conformance with the latest NEC®. The ElectriCalc Pro is a complete electrical reference tool that will save you time and money.

The official ElectriCalc® Pro from Calculated Industries for iPhone is a full-featured emulation of our popular ElectriCalc Pro handheld calculator.

Work directly in and convert between Amps, Watts, Volts, Volt-Amps, kVA, kW, PF% and EFF% and DC Resistance

Calculate wire sizes per NEC® 310-16 and 310-17; Copper or aluminum, 3Ø/1Ø, 60°C, 75°C, 90°C insulation ratings and 100% or 125% of ampacity. Can also adjust wire sizes for ambient temperatures other than 30◦ C and for more than three wires in a raceway

Conduit sizing for 12 types of conduit. Per 2005 and 2008 NEC® Table C1-C12, find sizing of all common conduits for any combination for #THW, #XHHW and #THHN wires. Plus, gives fill percentages, cross-sectional areas, remaining areas and more

Find Motor Full-Load Amps per current NEC®. Works in 1Ø and 3Ø with the new expanded tables for 3Ø induction (to 500 hp) synchronous (to 200 hp) and DC motors per NEC® 430-247, 430- 248 and 430-250.

Nice replication of a current standard. Very useful. Would be nice if you could also switch to a different UI that would be more suited to a touchscreen device, and make the relevant information more readily viewable, ie. an editable (printable) list view of all the parameters input by the standard interface.

Excellent App5 out of 5.0
